Ptychitoidea, formerly Ptychitacheae, is a superfamily of typically involute, subglobular to discoidal Ceratitida in which the shell is smooth with lateral folds or striations, inner whorls are globose, and the suture is commonly ammonitic. Their range is Middle_ and Upper Triassic.
Fossils of Ptychitoidea have been found in the Triassic of California and Nevada in the United States; British Columbia and Nunavut in Canada; Italy, Switzerland, and Hungary in Europe; Russia, China, and Afghanistan in Eurasia; Tunisia, Oman, Malaysia, and Papua New Guinea.
